Service settings

Common settings

Service ID

The service ID (SID) of this Mobius service. This entry is populated automatically when the service is add to the configuration and should not be modified by the user.

Host URI

The host URI (including its port) tells the service which Mobius hub to connect to. This entry is populated automatically when the service is add to the configuration and should not be modified by the user. The default is the local device.

Enabled

If checked this service is enabled and may be started either manually or automatically on boot. The default is checked.

Run At Start

If checked this service will start running automatically when the device boots up. For most services this should be checked. The default is checked.

Raw JSON

All of the settings below the raw JSON switch are service dependent. They are stored on the device in the JSON format but for ease of use, most services provide a simple custom user interface for configuring the required custom settings. Advanced users may choose to directly edit the JSON. Setting the raw JSON switch to true will hide the custom user interface and show the settings in JSON format. Setting the switch back to false will once again show the custom user interface.
